NEW YORK -- Books have been a bit of the orphan in the digital world. Music has the iPod. Video has YouTube. Books have, well, Amazon.com, where you can buy them printed on paper.

Sure, there are electronic books available for download at Amazon and elsewhere, but they haven't caught on. Sony Corp. is now tackling part of the problem with the U.S. launch of the first e-book reader that imitates the look of paper by using an innovative screen technology.

Is this the iPod for books? Not quite. But it is a step forward.

The Sony Reader is a handsome affair the size of a paperback book, but only a third of an inch thick. It's on sale for $350 on Sony's Web site and will hit Borders stores in October.

The 6-inch screen can be taken for a monochrome liquid-crystal display at first glance, but on closer inspection looks like no other electronic display. It's behind a thin pane of glass, but unlike an LCD it shows no "depth" -- it pretty much looks like a light gray piece of paper with dark gray text.

The display, based on technology from Massachusetts Institute of Technology spinoff E Ink Corp., is composed of tiny capsules with electrically charged particles of white and black ink. When a static electric charge is applied on the side of the capsule that faces the reader, it attracts the white particles to the face of the display, making that pixel show light gray. Reversing the charge brings the black pigments floating through the capsule to replace the white pigments, and the pixel shows as dark gray.

Like paper, the display is readable from any angle, but it doesn't look as good as the real thing, chiefly because the contrast doesn't compare well. The background isn't white and the letters aren't black. The letters show some jaggedness, even though the resolution is a very respectable 800 by 600 pixels. It will display photos, though they look a bit like black-and-white photocopies.

But it's still a more comfortable reading medium than any other electronic display. The text is easy on the eyes in almost any light you could read a book by.

The other major advantage of the display is that it's a real power sipper. Sony says a Reader with a full charge in its lithium battery can show up to 7,500 pages, an amazing figure that I unfortunately didn't have the time to test.

The reason behind this trilogy-busting stamina is that the display only consumes power when it flips to a new page. Displaying the same page continuously consumes no power, though the electronics of the device itself do use a little bit.

The Reader's internal memory holds up to 100 books, depending on their size. The memory can be expanded with inexpensive SD cards or Memory Sticks.

To load books, connect the Reader with a supplied cable to a Windows PC running the accompanying software. You can transfer Word documents or Portable Document Format files to the Reader, download blog feeds, or buy e-books at Sony's online store. It will also play MP3 music or audiobook files.

The store's interface looks comfortably like that of iTunes with major titles from publishers such as HarperCollins, Simon and Schuster and Penguin-Putnam. In keeping with the e-book market so far, there's no big price break: The electronic version will cost a dollar or so less than the printed book.

The Reader would be a perfect companion for the avid book reader, but for a few things.

First of all, navigation is fairly clumsy. You can't just enter the page number and jump to the page, nor can you enter a word or phrase to search for, as you can when reading a book on a PC. To get around, there are 10 buttons that will each take you a 10th of the way through text. You can also jump to chapter starts, or return to bookmarks. Still, this is very much a one-way device, designed for reading a book straight through from cover to cover.

This lack of interactivity is partly because the screen is slow to change, since it takes time for the pigments to move through the capsules. It takes about a second to display a new page. That means no scrolling through pages, and no note-taking on the screen -- imagine having to wait a second for each letter you write to appear.

Secondly, and less importantly, the Reader handles PDFs poorly. It doesn't allow you to zoom in on them, so if they're formatted for standard 8.5-inch-by-11-inch pages, the text will be illegibly small.

Thirdly, the Reader doesn't have a built-in light source, unlike PCs and personal digital assistants. A small clip-on light of the kind sold for books should work well, though.

Because of these drawbacks, it's hard to see the Reader as something that will bust the e-book market open. But it deserves a much better reception than the generally small LCD-based devices that hit the market a couple of years ago, some of which are already discontinued.

Other competition comes from cell phones and PDAs, but none of them match the Reader for screen size, legibility and battery life. Laptops, Tablet PCs and tablet-style Ultra-Mobile PCs have the screen size, but are heavier, more expensive, take time to boot up and have short battery lives.

The real competition, though, will be printed books, which have so far defeated all digital contenders with their excellent "battery life" and "display quality."

Sony's going to have to try a little harder before it can really start saving trees.
